@brief Set endpoint for version verification

This API can be used for setting an application specific protocol version which can be verified by clients through the endpoint.

@note

  • An endpoint must be bound to a valid protocomm instance, created using protocomm_new().

@param[in] pc Pointer to the protocomm instance @param[in] ep_name Endpoint identifier(name) string @param[in] version Version identifier(name) string

@return

  • ESP_OK : Success
  • ESP_FAIL : Error adding endpoint / Endpoint with this name already exists
  • ESP_ERR_INVALID_STATE : Version endpoint already set
  • ESP_ERR_NO_MEM : Error allocating endpoint resource
  • ESP_ERR_INVALID_ARG : Null instance/name/handler arguments
